GEORGE B. WEAST, OF NEWVILLE, PENNSYLVANIA.

SHEET-METAL ROOF.

EiPIElCIPICATION forming part of Letters Patent No. 329,789, datedNovember 3, 1885.

Application filed December 18, 1884. Serial No. 150,649. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE B. WEAST, residing at Newville, in the countyof Cumberland and State of Pennsylvania, have invented a Sheet-MetalRoof, of which the following is a specification.

The invention will first be described inconnection with the drawings,and then pointed out in the claim.

Figure 1 of the drawings is a view showing my invention as appied. Fig.2 is a crosssection through line 00 5c of Fig. 1. Fig. 3 is a plan viewof the shingle, showing its construction on the upper face. Fig. 4'is atransverse section of the roof and cap.

In the drawings, A represents my metallic shingle made of sheet-tin, andB is a sheathing or roof-frame, to the transverse pieces I) of which theshingles are nailed at diagonallyopposite corners.

*1 preferably make my shingle'in an approximately rectangular form,although the shape may be greatly varied without departing from theprinciple of my invention.

A represents the roof-cap. It will thus be perceived that thefastening-nails are in a diagonal line at right .angles to the pitch orinclination of the roof, while the complementary angles of the rectanglewill be bisected by a line drawn in the-same direction as the pitch. Inthis line of bisection I make the groove a, and on each side thereof thebranch grooves a, inclined thereto and terminating therein.

By this construction a series of water-channels are provided, so as togather the water and guide it off the shingle and finally into theeaves-trough. I prefer to make these grooves 11 a by corrugating themetal, so as to make them more rigid and less liable to be bent by windor other force. On two opposite sides of the shingle I make thesubjacent folds a a and on the other two sides the superposed folds at asaid folds a a forming hooks which interlock and unify the roof, as ifall its parts were integral. The shingles are thus made to cooperate inresisting wind, rain, or storm,

and the roof is a very permanent one, little liable to get out of order.Of course, like every other metallic roof, this should be well paintedto prevent oxidation.

I am aware that the grip-lock is not new, and that grooves have beenused in sheet-metal shingles; but I know of none in which my longpitch-groove a, with all the branch grooves opening into it, has beenemployed; hence What I claim, and desire to protect by Letters Patent,is-

A metallic shingle having the long groove a running from top to bottomwith the pitch of the roof and all the oblique branches a openingthereinto, as shown and described.
